What I Know Is (wiki) or Perhaps Not?

Our entire purpose in the world is to live and survive as human organisms, some people like to believe that we have a higher purpose as human beings because we (all of us) in the world want to believe that, but that does not make it a fact, it is just wishful thinking. Only by asking questions to reach a consensus creates our facts, all that we know is either fact or fiction. Our permanence is in our deeds that we do in life, believe it or not, soon 300 more years will go by, what will matter to us then? What will we know? Will we know any more than we do now?
